The weekday and weekend shared parking demand analyses are based on the ULI shared parking methodology. City parking ratios, as presented in Table 2, were utilized to calculate the base peak parking demand to which the hourly factors were applied. As shown in Tables 3 and 4, the hourly variation in total parking demand for a weekday and weekend day is identified. Only a few hours of each day are shown to experience peak demand levels. For a typical weekday, the peak parking demand is forecast to occur at 1 :00 PM with a demand of 533 spaces (Table 3). With an on-site parking supply of 505 spaces, the project site is forecast to have a parking deficiency of 28 spaces. For a weekend day, Santa Ana Downtown Plaza is forecast to experience a peak parking demand at 2:00 PM with a demand of 525 spaces (Table 4). With an on-site parking supply of 505 spaces, the project site is forecast to have a parking deficiency of20 spaces. Based on the theoretical shared parking analysis, Santa Ana Downtown Plaza will have parking deficiencies at 1 :00 PM, 2:00 PM, 7:00 PM, and 8:00 PM on a weekday, and 2:00 PM and 3:00 PM on a weekend day. It should be noted that these parking deficiencies are based on generic parking utilization profiles not specific to the project site. As shown in Table 1, a few of the existing tenants close at or prior to 7:00 PM on a weekday or are closed on Saturday and/or Sunday. As such, the theoretical shared parking demand forecast for a typical weekday and weekend day may be too conservative and not representative of actual conditions at the Santa Ana Downtown Plaza. Therefore, an additional shared parking analysis for Santa Ana Downtown Plaza was prepared based on actual parking surveys at the project site to determine realistic parking demands. The findings of this analysis are presented in the following sections of this report. PARKING SURVEYS To determine the current parking demand characteristics of the existing uses at Santa Ana Downtown Plaza, parking surveys were conducted by Transportation Studies, Inc. (TSI) on a "typical" weekday and weekend. The parking surveys, which were performed at one-hour intervals between 8:00 AM and 10:00 PM and consisted of counting the number of parked vehicles within the on-site surface lot, were conducted on Thursday, August 26, 2004 and Saturday, August 28, 2004.
